3D real-scene reconstruction after earthquake

(1) Rapid restoration of the disaster scene without dead angle observation

(2) Reduce the labor intensity and operational risk of investigators

(3) Improve the efficiency of geological disaster emergency investigation

At 23:50 on February 6, 2018, an earthquake of magnitude 6.5 occurred in the sea area near Hualien County, Taiwan (24°13′ N —121°71′ E). The focal depth was 11 km, and the whole Taiwan was shocked.

The earthquake occurred on August 3, 2014 in Ludian, Yunnan Province. The rapid 3D imaging function of UAV oblique photography can restore the disaster scene through 3D images, and can observe the target disaster area without dead angle in a few minutes.

Mud-rock flow and landslip

(1) Directly to see the houses and roads after disaster

(2) Post-disaster assessment of landslides

In December 2015, the National Geographic Information Bureau of Surveying and Mapping built a 3D of the real scene for the first time to know the disaster situation of houses and roads intuitively, which played an important role in after-rescue.

On August 12, 2015, a sudden landslide accident occurred in Shanyang County, Shaanxi Province, which resulted in dozens of deaths. Landslides make roads impassable. UAV oblique photography has its unique advantages in this area. Due to the 3D model,the rescue and excavation of landslides can be carried out efficiently .

3D real-scene model of explosion in Tianjin

On August 12, 2015, the explosion of Tianjin Binhai New Area shocked the whole country. In the large-scale hazardous chemical explosion area, drones became the most effective “explorer”. The drone is not a simple "pathfinder", and completed the oblique photography task of the accident scene, and quickly generated a realistic 3D model , which played an important role in the follow-up disaster recovery and rescue command .
